    Castle Rock is a limestone pillar that rises 196 feet above the ground just outside of the city of St. Ignace. The spire, or sea stack, was created by erosion from the lake and by ancients glaciers which once covered the region. Now, Castle Rock is a tourist attraction and provides great views of Lake Huron.
